Tru-maxx 66253255571 Surface Grinding Wheel 6in 60 Grit

Product Description

The TRU-MAXX 66253255571 is a Type 1 surface grinding wheel designed for precision stock removal and surface finishing on ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and good form-holding under repeated use. It measures 6 inches in diameter, 1/2 inch thick, and carries a 1-1/4 inch arbor hole. The 60 grit, K hardness (medium grade) spec makes it well-suited for moderate material removal where surface finish and wheel life need to be balanced. It is rated to a maximum of 5,410 RPM. The semi-friable grain structure promotes self-sharpening action during use.

This wheel is intended for use on surface grinders in tool rooms, maintenance shops, and production grinding environments. The Type 1 straight-wheel profile fits standard surface grinder spindle setups. The aluminum oxide abrasive is appropriate for grinding carbon steels, alloy steels, and similar ferrous workpieces. The medium grade and 60 grit combination suits roughing and semi-finishing passes where the operator needs controlled material removal without aggressive wheel breakdown. The non-porous, vitrified bond holds the abrasive structure firmly, supporting accurate flat-surface and angular grinding work.

Installation Notes

Mounting and dressing of grinding wheels should be performed by qualified personnel following ANSI B7.1 safe-use standards. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test. Never exceed the maximum RPM stamped or listed for the wheel.
